Central and eastern are the only two readily available to anyone. The
pictures I sent are of centrals, and the ones Chip sent ( was you Chip ,
right?) were of easterns. The central is a barred fish, and the eastern a
striped one. They are pretty much identical otherwise.

Average is two to three inches, but I have caught centrals over seven
inches. These are very rare fish, and not likely to grow this large in a

They are great hunters. Any fish they can fit in there mouth is lunch sooner
or later. An adult male guppy would be lunch, fins and all. I think average
muds would have trouble with the more robust female guppy.

Termites would be great. Earth worms - experiment. Keep trying larger
pieces. I would suggest not going too big though. An adult should be able to
eat half inch sections of night crawlers, which are quite girthy.

Yup. Experiment and find what works best for you. You can ask further
questions as they arise.

I would call it sparring. They will challenge other species. Anyone who is
willing to flare gills and face off. I have had muds spar with small
sunfish, it is really entertaining. These sparring matches have never
resulted in anyone getting hurt in my experience. Large muds can harm small
fish though, since they would hit them with more force than the small fish
can handle. Usually after one of these run ins, the small fish will flee,
and the mud will feel vindication and let that fish be. As a result, the
small fish will avoid being in that situation again.
